Trigonometry and Pythagoras I want to focus in this post on the differences between trigonometry and pythagoras. When to use each one and so on. Let’s start by reminding ourselves of the equations you will hopefully be familiar with by now, presuming you have
I’m going to write a series of posts about quadratic equations over the next few weeks which will hopefully clear up the confusion about them and lead to you, the reader, becoming an expert on the topic of quadratic equations. This is my plan
Organ Systems: Circulatory At the time of writing this blog post I am 42 years old. For 42 years, my heart has kept me alive, pumping blood around my body carrying oxygen, glucose and other nutrients to every cell in my body via a
What is seeing? If you are anything like me, you have already come across questions such as “How do you know the red that you see is the same as the red I see?” discussed here on Vsauce by the one and only Michael
What is seeing: Part 2: You see with your… …Your ears? The boy you see riding the bike on the right is called Ben Underwood. When he was 2 years old he was diagnosed with retinal cancer and if left untreated could spread to
How do you see? It seems a fairly basic question with a fairly obvious answer, doesn’t it? But let’s think about it a little bit… I’m currently in my garden looking at a tree. There are birds flying around and I can hear them
When you start thinking about writing your personal statement, it can be more challenging if you’re applying for a subject which is not commonly taught in schools. Engineering is a very popular course choice with great career and development opportunities. It also has a
Today I am covering series and parallel circuits. In my last two posts I wrote about charge, current and voltage, and then about resistance. I tried to give a clear picture of what each one is and what it is not. If you have
As part of the A-level practical endorsement, and on the exam papers, you will be expected to show competence in answering uncertainties questions in physics. Uncertainties questions in physics are almost always in the context of a practical, and they tend to follow a
Electrical resistance and Ohm’s law In my last post, I wrote about a fairly extensive piece on charge, current, and voltage in electricity. I said some things have something called charge and some things do not. Like charges repel, opposite charges attract. Electrons all
Physics Practice Questions. Think of all the homework and class assignments you have been set. How many of them involve working through exam questions? Some? Most? All? Chances are, if you’re studying Physics A-level or GCSE you’ve been set work that includes previous
What is Electricity? A lot of students struggle with this topic and just like with many topics, the problem lies within the foundational understanding. A student may be struggling with how voltage and current behave in series and parallel circuits but has not noticed that
